Abstract
Abstract An endoscopic instrument comprising an elongate body having a proximal end and a distal end. Actuating mechanism is located at the proximal end and operating mechanism at the distal end. The operating mechanism comprises a pair of V-shaped jaw members, a cautery wire associated with jaw members to incise tissue gripped by the jaws and a mucosa-protecting balloon attached to and movable with one of the jaw members.
